Identification of two new proteins in spermidine nucleoids isolated from Escherichia coli.

ABSTRACT: The Escherichia coli nucleoid contains DNA in a condensed but functional form. Analysis of proteins released from isolated spermidine nucleoids after treatment with DNase I reveals significant amounts of two proteins not previously detected in wild-type E. coli. Partial amino-terminal sequencing has identified them as the products of rdgC and yejK. These proteins are strongly conserved in gram-negative bacteria, suggesting that they have important cellular roles.
